wand of polymorph vs monster inventory

From the newsgroup:  inventory dropped by a monster killed by system
shock when zapped by a wand of polymorph is protected against being poly'd
by that same zap, but worn/wielded equipment that's forced to be dropped
due to being unusable in a transformed monster's new form was not.  Not
mentioned in the newsgroup, but also fixed:  boulders dropped when a giant
turns into a non-giant were also subject to the zap instead of protected.
